The Zoom City Carbon Model - ZCCM is a high-resolution, bottom-up framework for quantifying urban CO₂ emissions at street-level granularity (100m grids). This interactive platform visualizes spatio-temporal emission patterns from key urban sources:Road traffic, Building energy, Human respiration, and Vegetation/soil interactions.

This Emission Geographic Information platform is designed to communicate the outcomes of the {ZCCM} to users, stakeholders, the research community, and the public in general. It enables the visualization of zoom CO2 maps and summary statistics of emissions in an interactive way.

This Flexdashboard R leverages road traffic estimates from the ZCCM::traffic model https://github.com/ByMaxAnjos/CO2-traffic-emissions to showcase the spatio-temporal variability of CO2 emissions at the city level. With this tool, users can explore detailed street-level emissions, emissions associated with Open Street Map features, and temporal patterns such as hourly time series, daily cycles, and monthly totals.
